To all whom it may concern.'

Be it known that l, JOHN F. Garenn- Donrnu, a citizen of the United States, re siding at Weimar, in the county of Placer and State oi California, have invented new and useiul Improvements in Armor for Automobile-Tires, ofl which the following is a specification.

llhis invention relates to means for protectiiig automobile tires, and particularly pneumatic tires, against punctureand Wear.-

lThe object of the Apresent invention is to provide :in armor for automobile tires 'which will' protect the same against wear ing Contact with lthe roadway, thus increasing the life of the tire and also eliminatingr the possibility of puncture.

llhe invention consists ot' an inner thin ooncavo-convex rim or shell, preferably of metal, conforming to the usual Wearing surface or tread or" a tire, and further of an outer shell or support on which is .mount ed a band or rim for carrying a soft tread which may be of rubber.

.The invention further consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in Which,-

Figure l is a cross section of one/form of the invention. Fig. 2 is a side elevation of a fragment thereof. Fig. 3 is a cross section of a modied form ofthe invention. Fig. 4 is a side elevation of a fragment thereof. .y

In that form of my invention shown in Fig. l, is a thin annular shell or .casing eircumferentially fitting the 'convex surface of an automobile tire, as 3, and to the lateral edges of the `shell 2, riveted 4or other- Wise secured, as at 4, are the contiguous edges of an outer annular converted part 5, which may be spaced from the convex surface of the shell 2 which fits ,the tire thereof.

ln Fig. l the parts 2 and 5 are so spaced as to form a crescent-shaped space in cross section, in which is centrally mounted an annular ring or spacing member 6 for spacing and supporting the parts 2 and-5, and circumferentiaiiy fitting uponv the outer surface of the protector part 5, is a hand or rim 7', the parts 7-65 and 2 being rigidly. secured by rivets,or other suitable means 8. Upon the rim or band 5 there andV held a cushion tread of rubber t'.

tionally held in place thereon.

From the foregoing, it will be seen that when the tire 3 is deiiated, the casing mein# ber 2 with its attached elements may be readily mounted upon the tire 3.' Upon indating the tire, the attachment will be frie- During the running of' the Wheel on which maybe mounted the cushion surface the Wear will occur on said cushion surface; the .load of the Wheel being transmitted to the surface through the associated shell members 2 and 5 and the supporting rim or band 7. A 4

ln Figs. 3 and e I have shown a slightly modiied forrn of the'invention in Which the tire fitting' rim 10 is substantially covered or incased in the protecting shellll; these parts being secured, edge to edge, by rivets 12, while the protecting part 1l hasv a flat tened peripheral surface 13 upon which is mounted the band lfl, ,this in turn support ing the cushion tread 15. The band 14 and the protecting member 13, with the tire litting shell 10, are all lrigidly secured by rivets 16.

By providing a easing' or member 10 adapted to snugly fit upon the tire and a casing or member protected against direct surface wear bythe outer shell or protector 11, it will be seen that the inner shell 10 may be made of light, substantial material. and the protecting shellV in turn is protected against direct Wearingacontact with the roadway by the cushion treadl, in one treads beine, respectively carried upon a substantial band or support, as 7, and 14, in the diiierent modifications; the greater part of the stress of operation being;r taken up by the heavier bands, and through these distributed to the thin shell-like nieinbels of the tire protector. y l

The function of the shells or thin metallic rings is to protect the sides of the tire from laceration and punctifre, and also to distribute the pressure, due to the encountering of obstacles and unevenness ofthe roadway, throughout a large portion of the tire. l

It is understood that the armor is placed on the tire when the held in place by the inflation of the tire; the ring 5 constituting'a supportingv and strengthening key to the arch ofthe transverse section of the armor. i

or tread '9 latter is deflated and 9c() instance, and 9 in the other case; these cation in which the lire ,is embraced by bhe shell lwhich is formeel; at its edges-to receive side flanges 2l of the rim; 22. rEllis rin; snppcrtsffblge' treed 23 which is bolted between deiueinble fiat. clamp rings 2 fil:- ting against 'seats 25'oftl1e rim 22. The Vrim is riveted to the shell 2O :is 26.

Haring thus described' my invention what, l-claim and vdesire to sentire by Letters Rin ent, ij: e

l. A tire armor comprising s relsively thin annular shell ,circulalerensinllj, fitting the surface of a, tire, an exterior annuler .shell protecting the inner shell, the con tiguous edges of said shells` seemed, 'a substantial annular band eneornpassing the anlerior portion of the outer shello said. shells and the band being rigidly secured, finden annular cushion tread member mounted u'pon the band for taking the weer, said shells protecting the tire against puncture ,and being held thereon entirely by friction. v

2. A faire armor comprising a, relativeljg thin annular shell circumferentially fitting `he bearing surface of ai tire, nn exiei'ior annular shell protecting the inner shell, the contiguous edges'of said shells being rigidly secureci e substantial annular band eneoin passing shell, said shells and the bend being rigidly being rigidly the anterior portion ef elle outer' secured, en annular Cushion member mount ed upon elle bend for taking tlie weer, said shells protecting be tire ngains puncture, anal n filler or specs tween and spacing said shells and being rigidly secured' fherevvilzh3 said tire armor being held in position by friction with `ille sire when the letter is inateel.

A cire armor comprising :i relaively li'l'iin annular shell circuniferentially tting the bearing surface of e tire, zijn exterior annuler shell pnoecting the inner shell, the eontignous edges of said shells meeting on the opposite sides of the tire incl being righ idly secure' together5 a substantial annular bend encompassing the anterior portion ol? the outer sliell,y saiil shells and the band being rigidly secured, a tread member mouille-:i upon the band, and n space mem-- ber interposed centrally between the shells end connected therewith, said lire armor losing held. in position by rclion of the tire when said. lire is inflated.

In testimony whereof l' have hereunto ses my hand elle presence or two subscribing `W-nbnesses, v
